What gains did organized labor make during the 1930s?

During the 1930s, organized labor made significant gains, particularly through the New Deal legislation which supported workers' rights and collective bargaining. The National Labor Relations Act of 1935, also known as the Wagner Act, empowered unions by protecting their right to organize and engage in collective bargaining. This period saw a surge in union membership and the establishment of major unions, such as the Congress of Industrial Organizations (CIO), which expanded the labor movement to include a broader range of workers in various industries. Overall, the decade marked a pivotal shift towards stronger worker protections and labor rights in the United States.
